Have you been asked to give a talk on your new WSPRlite at a local ham
gathering or radio club? We have made it easy with this downloadable
MS PowerPoint presentation. Feel free to alter it to suit your own
audience. Let us know how it went!WSPRlite presentation

Configuration app

The WSPRlite configuration app is used to change the callsign, locator, and other settings for your WSPRlite.

System requirements: Windows Vista / 7 / 8 / 10.
Windows XP and older are not supported. Linux version might be available soon. Mac is not officially supported. The source code is cross platform, and is tested on Windows and Linux.

Drivers

Before using the config app on Windows, the "CP210x USB to UART Bridge VCP" driver needs to be installed. Note: the zip file must be unzipped into another folder before installing.

Random selection of transmit timeslots is now the same for all WSPRlites (if they have the same repeat rate setting), instead of being different every time the button is pressed. This allows WSPRlite transmissions to be synchronised.
